Note:
The device content disclosed herewith is approximate and is based on engineering estimates only. It has not been verified through analytical
testing. Additionally, the following should be noted:
1. One or more dopant materials may be present in the silicon die to provide semiconductor properties.The amounts are very small and estimated
as listed.
2. Epoxy resin components listed are generic and may or may not be the specific compound used, which is considered proprietary.
3. Brominated epoxy resins listed are generic and may or may not be the specific chemical used. The identity of the compound used is
proprietary, however National certifies that these brominated compounds are not PBB or PBDE's, which are banned.
4. The die attach, if present, does not contain any flame retardant.
